Entropy, 25(3), 501.1099-4300http://dx.doi.org/10.3390/e25030501https://hdl.handle.net/20.500.12491/11364The non-Markovianity of open quantum system dynamics is often associated with the bidirectional interchange of information between the system and its environment, and it is thought to be a resource for various quantum information tasks. We have investigated the non-Markovianity of the dynamics of a two-state system driven by continuous time random walk-type noise, which can be Markovian or non-Markovian depending on its residence time distribution parameters. Exact analytical expressions for the distinguishability as well as the trace distance and entropy-based non-Markovianity measures are obtained and used to investigate the interplay between the non-Markovianity of the noise and that of dynamics. Our results show that, in many cases, the dynamics are also non-Markovian when the noise is non-Markovian. However, it is possible for Markovian noise to cause non-Markovian dynamics and for non-Markovian noise to cause Markovian dynamics but only for certain parameter values.eninfo:eu-repo/semantics/openAccessTwo-State SystemNon-MarkovianityContinuous Time Random WalkNon-Markovian NoiseLaplace TransformsNumerical InversionArticle10.3390/e25030501253112369813892-s2.0-85152412592Q2WOS:000956711200001Q2
